I have two fursonas, Rocco the anthro GSD and Kyr'am the feral wolf. They each are an amplified part of me, and I have them coming from a situation similar to mine. I try to be Rocco, but I feel Kyr'am come out at times.
Rocco has been isolated from other furs for over a decade. He's quiet, but tries really hard to speak. He's willing to try stuff, even stuff I would never consider, like dancing, but won't do what he sees as wrong. Very strong sense of right and wrong. Loves to help and make others laugh. He's trying to reintegrate to society and find friends, but first he has to figure out what a friend is and what they do. He is kind of shy and awkward, just because he hasn't been around others for so long. He also tries to be funny, with mixed results. He has some trust issues and paranoia, but is trying to get over them. He likes happy music. Extremely loyal once he accepts someone. Still some topics he doesn't want to talk about, but he is continuing to open up over time.
Kyr'am, which means death in Mandalorian, is an amplified version of my dark side. He very rarely talks to anyone. He sees others falling into three categories. Allies, neutral, and enemies. And he even plans contingencies in case he needs to kill his allies. He doesn't know what a friend is, and he doesn't care. He feels an incredible power inside himself, one he uses to conquer any challenge and mercilessly destroy any opponent. He trust no one, not even his allies. He is angry, hateful, and paranoid. He enjoys death. He is gruesome. He is perfectly happy just to hide in a cave all day and not see anyone. The ends justify the means almost every single time. He is, quite literally, a monster. He listens to war music only.
